WILLIAM GUNN PRICE, OF NEW CASTLE, PENNSYLVANIA.

BRAKE-HANGER.

Application filed November 25, 1911.

To aZZ whom it may concern:

Be it known that 1, WILLIAM GUNN PRICE, a citizen of the United States,and resident of New Castle, in the county of Lawrence and State ofPennsylvania, have invented a new and useful Improvement inBrakeHangers; and I do hereby declare the following to be a full, clear,and exact description thereof.

My invention relates to brake hangers.

The object of my invention is to provide a brake rigging in which thehanger supporting the brake-shoe is held againstundue lateral movementwhereby the brakeshoe is always held in proper relation to the wheelwhere the brakes are released or applied, while at the same time thewear on the connecting parts is reduced to a minimum.

To these ends my invention comprises, generally stated, a suitablebracket or support, a brake-hanger suspended therefrom, a brake-shoehead secured to said brakehanger, and means for preventing lateralmovement of the brake-hanger, whereby the brake-shoe is held in properalinement with reference to the tread of the wheel.

In the accompanying drawings Figure 1 is a side elevation of a portionof a truck showing my invention applied thereto. Fig. 2 is a section onthe line 22 Fig. 1. Fig. 3 is a section on the line 3-3 Fig. 1; andFigs. 4, 5 and 6 show modified forms of my invention.

In the drawings the numeral 2 designates a suitable truck framesupported on the wheels 3, the springs, journal box, etc., being of anysuitable construction. The truck frame is further provided with theequalizer bars 4: which extend from one journal box to the other. Thebracket 5 is supported by the equalizer bars 4 and said bracket issecured to said equalizer bars by the bolts 6. The shims 7 may beinserted between the bracket 5 and the inner faces of the equalizer bars4 for adjusting the bracket to and from the wheel, as may be foundnecessary to get the proper adjustment. The upper end of the bracket hasthe projection 8 which may be conical in form and said projection entersa corresponding recess 9 in the upper end of the hanger 10. A bolt 11passes through the upper end of the bracket 5 and said bolt secures thehanger to said bracket. A strong spring 12 surrounds the Specificationof Letters Patent.

Serial No. 662,458.

bolt 11 and said spring is compressed between the bracket 5 and the nut12 on said bolt so as to give a frictional pivot to resist the swingingmovement .of the hanger 10 whereby the shoe is held up in properrelation to the wheel, all as contained and set forth in a patentpreviously granted to me No. 818,639.

The brake-shoe head 13 is secured to the lower end of the hanger 10 bythe bolt I l. The brake hanger has the cylindrical projection 15 whichenters a recess 16 in the brake-shoe head 13. The spring 17 isinterposed between the hanger 10 and the nut 18. This spring acts tohold the brake-shoe up in proper relation to the wheel and prevents thesagging or tilting of the shoe and the uneven wear consequent thereto.Further the spring 17 and bolt 14 will be amply able to prevent theseparation of the top of the brake-head from the hanger by the downwardpull on the head caused by the wheel during a brake application. In thismanner a single hanger 10 may be employed which is pivoted at its upperend to the bracket or support 5 and is connected at its lower portion toone side of the brake-shoe head.

The main object of my invention is to support the hanger 10 againstlateral movement so as to hold the brakeshoe head in proper relation tothe tread of the wheel where a single hanger is employed, and where nobeam is used. This may be accomplished in a number of different waysall. of which come under the broad scope of my invention, and I haveillustrated several forms. In the first form the lower end of the hanger10 extends below the connection with the brake-shoe head, and isbifurcated by the off-set 19 to form a recess 20. This recess 20 isengaged by the guide-plate 21 which is secured to the equalizer bars 4:by the bolts 22. A suitable wear plate 23 is also secured by the bolts22 to relieve the equalizer bars of any wear.

Washers 25 are interposed between the wear plates 23 and the equalizerbars and said washers may act as spacing shims to adjust the lower endof the hanger or to take up any wear and prevent any undue movement ofthe hanger of the guide. In this manner the lower end of the hanger isfree to swing horizontally the necessary amount to apply and release thebrake-shoes as well as for the swinging back of the brakehanger when itis desired to renew the shoes. The brake-hanger, however, is guided andheld against lateral movement by the engagement of its bifurcated endswith the guide plate so that the lateral movement of the shoe isprevented and the shoe held in proper alinement with the wheel to givean even wearing to the same.

The brake shoe head is cut away as at 13 and its upper and lower endsbear against the inner face of the hanger 10, and as the hanger extendsfor the full length of said head, said head is supported along its outerface at the upper and lower ends, so as to hold said head in properalinement and prevent its tilting laterally. I prefer to have the headcut away as at 13*, so that the head will bear at its upper and lowerend against the inner face of the hanger and give more even V9311 Thelive lever 26 is pivoted at its lower end to the adjusting bar 27 and isconnected to the lug 28 of the brakeshoe head while the upper end ofsaid lever is connected to the ordinary operating rod 29. By dispensingwith the brake-beam and by using a single hanger located on the outsideof the brake-head, so that there is no obstruction to the movement ofthe lever 26, the brake-lever 26 is arranged vertically instead ofdiagonally, as in the case where double brake-hangers are employed, andit is placed to one side so that said lever and the brakehanger do notin any way interfere with the location of the motor.

In Figs. 4 and 5 I have illustrated a modified form of my invention inwhich a bracket 30 is secured by bolts 30 to the side frame 31 of thetruck, said bracket having the projection 32 which enters a conical seat33 in the hanger 34, a bolt 35 passing through the hanger bracket andside frame secures the' hanger to the bracket and a spring 35 isinterposed between the side frame and the nut 36. The bracket 30 has thedownwardly extending arm 37 which is adapted to engage the recess 38formed between the hanger 34 and the off-set 39 on said hanger. Thelower end of the hanger 34 has the projection 40 which enters the recess41 in the brake-shoe head 42. A bolt 43 connects the hanger with thebrakeshoe head. A spring 44 in said bolt is interposed between saidhanger and the nut 45. In this modified form of my invention the guidingmeans for holding the hanger against lateral movement is located abovethe connection of the hanger with the brakeshoe head and the guiding arm37 on the bracket 30 prevents any undue lateral movement of the hanger.The hanger is in this instance supported by the truck frame and notcarried directly by the equalizer bar as in the former instance, but bythe bracket and engaging tllGIQWlth;

30 connected to the side frame of the truck, and the guiding memberforms part of the bracket.

In Fig. 6 I have illustrated another modified form of my invention inwhich the hanger 47 is carried as before by the bracket 5 supported bythe equalizer bars 4. However, in this case the guiding member 48 isconnected to the bracket 5, and said guiding member engages the seat 49formed between the hanger 47 and the off-set 50.

1. In brake rigging, the combination of a suitable support, a singlebrake hanger suspended therefrom, a brake-head, a pro-jection on oneside of said hanger entering a seat formed therefor in said brake-head,a bolt passing through said projection and head, and said head incontact with the adjacent face of said hanger.
